AGP je obycajna PCI (napr z voodoo3 je rozdiel nulovy) jedine vyhody v
rychlosti sa dosahuju pomocou AGP featur (priamejsi pristup k pemeti
grafiky, textury ...) ale mam dojem ze FB je akurat vec ktoru to
urychly.

First they came for the Communists,
     and I didn't speak up,
         because I wasn't a Communist.
Then they came for the Jews,
     and I didn't speak up,
         because I wasn't a Jew.
Then they came for the Catholics,
     and I didn't speak up,
         because I was a Protestant.
Then they came for me,
     and by that time there was no one
         left to speak up for me.
